Application filed November 7, 1907. serial No. 401,139.

To all whom t may concern:

Be it known that I, AUGUST ABRAMsoN, a citizen ofthe United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Gas-Heaters, of which the following is a specification.

My invention relates to certain improvements in apparatus for heating sad irons and such articles by the use of gas and compressed air.

The main object of my invention is to so design'such a heating apparatus that it will' automatically light and extinguish the heating liame g and a lfurther obj ect is to provide a suitable mixing chamber and means for regulating the ame. These objects I attain in the following manner, reference being had to the accompanying drawings, in which:-

Figure l, is a vertical sectional view of my improved gas heater; Fig. 2, is a'sectional plan view on the line 2 2, Fig. l; Fig. 3, is a side view; and Figs. 4: and 5, are perspective views of details.

A is .a standard having a base A and mounted on this standard is a double support a, of, in the present instance for thereception of a sad iron. One support o'. is provided with a gas heater and the other support a is to rest the iron upon without heating, but it will be understood that my invention can be applied to any form of support.

B is the burner having a slotted cover plate l) forming a iinal mixing chamber for the air and gas. This burner is connected by a vertical pipe b with a valve casing D, and also connected to this casing are the gas and air pipes C and E, respectively. The gas pipe C is connected to a T-joint c which in turn is connected to the casing D by a thimble c. The T-joint cis connectedtoa pipeF extending to a point near the burner B and is provided with a small burner f, forming a pilot light for the main burner B. In the pipe F is a cock f for regulating'the supply of gas to the pilot burner. The air pipe E in the present instance is connected to the lower portion ofthe casing by an elbow oint e and thimble I prefer to so connect the air and gas pipes that the air pipe will be in direct line with the burner pipe b and that the gas pipe will project the gas into the path of the air under pressure, the mixing taking place first in the valve casing D and 'finally in the burner B. From the above description it will be seen that of the four pipes connected to said casing D two project from itstop and bottom, while the remaining two project from opposite sides respectively.

d is a valve having a stem d which is forked and screw threaded. On the stem is a coiled spring g tendin to force the valve against its seat to close t e gas passage leading from the pipe C; a cap d2 holds the spring in position.

Passing through the slot d3 in the forked end of the stem d is an arm fi forming part of a rod I; This arm is made as shown in Fig. 4, having a T-head i so that it cannot be accidentally detached from the stem d; a nut d3 on the threaded end of the stem d regulates the opening of the valve so that more or less gas can be admitted to the burner, as desired. The rod I is connected to one arm of a bell crank lever N, pivoted at n to a bracket M adjustably secured to the stem A. The bracket is forked to form a clamp and is held by means of a screw m. The other arm of the bell crank lever N is attached to a presser rod P extending through the support a and has a head p rounded on one side as at y0. y The head of this rod extends above the projections a3 forming the supports for the sad iron, as illustrated in Fig. 1, so that when the sad iron is placed on the support it Vforces the presser rod down causing the rod I to withdraw the valve and allow gas to enter the valve chamber D, which mixes with the air under pressure and is ignited at the burner B by the pilot light The head of the rod P is rounded on one side so that when the operator places the iron on the support it will not catch on the head but will slide over it and press it down.

I claim 1'. The combination of a standard, an iron supporting structure mounted thereon, a burner for said structure, a valve casing having four branches extending from its top, bottom and opposite sides respectively, of which one branch is connected to the burner, a gas supply pipe connected to a second branch, a valve for said pipe having a rod projecting through the third branch and in i a burner, a valve casing communicating vwith and connected to the valve rod, substantially 10 the burner and with gas and air pipes, a as c lesorihed.

valve in the' easing arranged to close the gas In testimony whereof, I have signed my pipe and leave the air pipe free, a spring on naine to this specification, in the presence of the stem of the valve, said stem being forked two subscribing witnesses.

at its outer end and threaded, a nut on the AUGUST ABRAMSON. threadedl end, a rod having a T-headed arln vVl/Yitnesses: adapted to the forked stein, and a presser JOHN POSNER,

rod extending normally above the support l BERTHA BODNICK.
